Laurie Magnus, The West Riding Territorials in the Great War (1920)
“ The only constant element in the Reserve units were the men, who, owing to age or health or other conditions, would never be fit for Imperial Service. Divisional and other military organization was the same in both Lines, but the 1st was composed of Officers and other Ranks ready for service abroad, the 2nd was composed partly of surplus Imperial Service personnel, partly of troops prepared, so far, only up to Home Service, which still formed the statutory function of the Territorial Force. ”
